and set digits to the flow volume increment required between relay pulses. Use
this feature for remote samplers, chlorinators or totalizers. Maximum pulse setting is
999,999. Minimum time between pulses is 1 second and pulse duration is 350
milliseconds. Selection of
Level
mode disables this function.

function.
Velocity
Press
È
to select velocity mode for the relay, then

R1Off
use

To calibrate a relay in level mode for echo loss only, set the relay On and Off points to
exactly the same value, then set
LOE
to On mode. The relay will now energize only
when a level echo loss condition occurs.
